¡La madrastra de mi amigo se sentó en mi cara!

My friend and I were going for a walk. I went to pick him up as usual, but he wasn't at home. His mom suggested that I stay at home and wait for him. She started asking me how I was doing with the girls. I'm not doing well and she offered to show me how to get a girl. She just took off her panties and sat on my face!
